尝试导入错误：当编译react-native到react-native-web时，不会从'./apiFetcher'导出'ApiGet'

Question

I am building react native app and it run successfully on both Android and iOS. I want to convert react-native app to web app. I try followed tutorial: https://medium.com/@jonnykalambay/your-first-hybrid-app-in-15-minutes-react-native-on-the-web-2cc2646051e as well as some source ( https://react-native-training.github.io/react-native-elements/blog/2018/12/13/react-native-web.html ). But when I run on web, there is error: Attempted import error: 'ApiGet' is not exported from './apiFetcher'.

My code:

//apiGet.js
function ApiGet(){
//some code
}

module.exports = {ApiGet}

//another file import
import {ApiGet} from './apiGet.js';

• I tried an example for testing with this syntax import, export. It run successfully. My code use both ES5 and ES6. When I run code in react-native, it's OK. I create a demo react-native-web using ES5, it's also OK.
